Notwithstanding its importance, it has been reported that as many as 2 billion people around the world have diets that are deficient in this important mineral, and even in affluent countries, such as the US, about 12% of the population is probably at risk of zinc deficiency. This figure raises to almost 40% if we take into consideration the elderly.
A new research has unveiled, for the first time, a biological mechanism by which zinc deficiency can develop with age, leading to a decline of the immune system and increased inflammation associated with many health problems, including cancer, heart disease, autoimmune disease and diabetes.
In other words, we should give zinc more credit, especially as we age!
